#Calculation is an ActiveX component designed for VB/VB.NET/VC++/VJ++/VC#.NET. It is a powerful calculation engine for your applications. This component integrates expression parsing and evaluating. Generally speaking, #Calculation is very useful in two general areas: first, when a formula has to be defined and evaluated at runtime (for example, if the end user is allowed to enter a formula that will be evaluated and used); second, when a set of formulas that depend on each other are defined, configured, and evaluated at run-time. #Calculation Component supports conventional math operators and functions and is suitable for heavy-duty number crunching. It also allows defining variables and sets of related formulas that implement spreadsheet-like recalculations. Even it can support Matrix and Array operation (just like MATLAB), note-line, different number system and custom-functions in your expression. The powerful calculation ability, various functions, and the different modes of work give power and flexibility.
